Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31572592, here are decompositions:

3 + 31572589 = 31572592
41 + 31572551 = 31572592
59 + 31572533 = 31572592
71 + 31572521 = 31572592
131 + 31572461 = 31572592
179 + 31572413 = 31572592
251 + 31572341 = 31572592
269 + 31572323 = 31572592

Showing the first eight; more decompositions exist.
